Susan wants to put up fencing around three sides of her
rectangular yard and leave a side of 20 feet unfenced. If
the yard has an area of 680 square feet, how many feet of
fencing does she need?

Answer Posted / sunil

area of rectangle is given by length*breadth
area is given as 680
if one side is 20 than
area 0f rectangle=l*b
680=20*b
b=680/20=34
so if three sides are fenced than total fencing will be
2*34+20=88
